Nordic Standard Tray-Type Cable Trays

Nordic cable tray systems typically follow international standards like IEC-61537 while offering standardized dimensions and materials suitable for Nordic installations.

Overview of Nordic Cable Tray Systems

In Nordic countries, cable trays are widely used for electrical and data cabling in industrial, commercial, and infrastructure projects. Leading manufacturers such as Nordic Wire Tray (NWT/X-Tray) and Meka provide a range of cable trays including wire mesh trays, ladder trays, and solid-bottom trays, designed for high durability and ease of installation . These trays are available in galvanized steel, stainless steel, and aluminum, with surface treatments to resist corrosion in harsh Nordic climates .

Standard Dimensions and Types

Typical Nordic cable trays follow these general dimensions:

• Length: 3000 mm standard, customizable for specific projects
• Width: 25 mm to 600 mm
• Height: 25 mm to 125 mm
• Tray types: Ladder, ventilated, solid-bottom, wire mesh, and compact trays Ladder trays are often preferred for heavy-duty cabling and wide spans, while wire mesh trays are used for lighter cabling and flexible routing . Many systems allow custom cutting, bending, and modular assembly to fit unique installation requirements .

Compliance with Standards

Nordic cable trays are generally designed to comply with IEC-61537, the international standard specifying requirements and tests for cable tray systems, including load capacity, mechanical strength, and electrical safety . Additionally, manufacturers may reference NEMA VE 1 and CSA C22.2 #126.1 for metal cable trays, ensuring compatibility with North American codes if needed . These standards cover:

• Material quality and corrosion resistance
• Load/span class designations
• Installation, handling, and maintenance guidelines
• Compatibility with power and control cables

Installation Considerations

Nordic cable trays are designed for fast and cost-effective installation. For example, X-Tray systems require only M8 bolts and basic tools for assembly, with fewer components and longer support spans to reduce installation time . Stainless steel trays are often used in food, pulp, and paper industries, or outdoor environments where humidity and corrosion are concerns .

Summary

While there is no single "Nordic cable tray standard," the region relies on international standards (IEC-61537, NEMA, CSA) combined with manufacturer-specific specifications for dimensions, materials, and installation practices. Nordic trays are designed for durability, flexibility, and compliance with electrical safety requirements, making them suitable for a wide range of industrial and commercial applications .
